Exactly Wrong

Greg Pavlik - Mon, 2014-07-21 08:58
I normally avoid anything that smacks of a competitive discussion on what I consider to be a space for personal reflection. So while I want to disclose the fact that I am not disinterested in the points I am making from a professional standpoint, my main interest is to frame some architecture points that I think are extremely important for the maturation and success of the Hadoop ecosystem.

A few weeks back, Mike Olson of Cloudera spoke at Spark Summit on how Spark relates to the future of Hadoop. The presentation can be found here:

In particular I want to draw attention to the statement made at 1:45 in the presentation that describes Spark as the "natural successor to MapReduce" - it becomes clear very quickly that what Olson is talking about is batch processing. This is fascinating as everyone I've talked to immediately points out one obvious thing: Spark isn't a general purpose batch processing framework - that is not its design center. The whole point of Spark is to enable fast data access and interactivity.
The guys that clearly "get" Spark - unsurprisingly - are DataBricks. In talking with Ion and company, it's clear they understand the use cases where Spark shines - data scientist driven data exploration and algorithmic development, machine learning, etc. - things that take advantage of the memory mapping capabilities and speed of the framework. And they have offered an online service that allows users to rapidly extract value from cloud friendly datasets, which is smart.

Cloudera's idea of pushing SQL, Pig and other frameworks on to Spark is actually a step backwards - it is a proposal to recreate all the problems of MapReduce 1: it fails to understand the power of refactoring resource management away from the compute model. Spark would have to reinvent and mature models for multi-tenancy, resource managemnet, scheduling, security, scaleout, etc that are frankly already there today for Hadoop 2 with YARN.

The announcement of an intent to lead an implementation of Hive on Spark got some attention. This was something that I looked at carefully with my colleagues almost 2 years ago, so I'd like to make a few observations on why we didn't take this path then.

The first was maturity, in terms of the Spark implementation, of Hive itself, and Shark. Candidly, we knew Hive itself worked at scale but needed significant enhancement and refactoring for both new features on the SQL front and to work at interactive speeds. And we wanted to do all this in a way that did not compromise Hive's ability to work at scale - for real big data problems. So we focused on the mainstream of Hive and the development of a Dryad like runtime for optimal execution of operators in physical plans for SQL in a way that meshed deeply with YARN. That model took the learnings of the database community and scale out big data solutions and built on them "from the inside out", so to speak.

Anyone who has been tracking Hadoop for, oh, the last 2-3 years will understand intuitively the right architectural approach needs to be based on YARN. What I mean is that the query execution must - at the query task level - be composed of tasks that are administered directly by YARN. This is absolutely critical for multi-workload systems (this is one reason why a bolt on MPP solution is a mistake for Hadoop - it is at best a tactical model while the system evolves).  This is why we are working with the community on Tez, a low level framework for enabling YARN native domain specific execution engines. For Hive-on-Tez, Hive is the engine and Tez provides the YARN level integration for resource negotiation and coorindation for DAG execution: a DAG of native operators analogous the the execution model found in the MPP world (when people compare Tez and Spark, they are fundamentally confused - Spark could be run on Tez for example for a much deeper integration with Hadoop 2 for example). This model allows the full range of use cases from interactive to massive batch to be administered in a deeply integrated, YARN native way.

Spark will undoubtedly mature into a great tool for what it is designed for: in memory, interactive scenarios - generally script driven - and likely grow to subsume new use cases we aren't anticipating today. It is, however, exactly the wrong choice for scale out big data batch processing in anything like the near term; worse still, returning to a monolithic general purpose compute framework for all Hadoop models would be a huge regression and is a disastrously bad idea.

Dependent Rational Animals

Greg Pavlik - Sun, 2014-07-20 16:32
I wanted to briefly comment on Alisdair MacIntyre's lectures collected as "Dependent Rational Animals", but let me precede that with a couple of comments for context: first, as I alluded in my last post referencing Levinas, it is my view that the the ethics demands a certain primacy in any healthy conception of life and society; second, in the area of ethics, Macintyre's After Virtue is the book that has had perhaps the biggest impact on my own thinking.

One of the criticisms of MacIntyre is that his critique of rational ethics is, on the one hand, devastating; on the other hand, his positive case for working out a defense of his own position - a revivification of social ethics in the Aristotelian-Thomist tradition(s) was somewhat pro forma. I think this is legitimate in so far as it relates to After Virtue itself (I believe I have read the latest edition - 3 - most recently), though I am not enough of a MacIntyre expert to offer a defensible critique of his work overall.

I do, however, want to draw attention to Dependent Rational Animals specifically in this light. Here MacIntyre begins with is the position of human as animal - as a kind of naturalist starting point for developing another pass at the importance of the tradition of the virtues. What is most remarkable is that in the process of exploring the implications of our "animality" MacIntyre manages to subvert yet another trajectory of twentieth century philosophy, this time as it relates to the primacy of linguistics. The net effect is to restore philosophical discourse back toward the reality of the human condition in the context of the broader evolutionary context of life on earth without - and this I must say is the most amazing part of this book - resorting to fables-masked-as-science (evolutionary psychology).

Big Data doom mongers need to look outside of the marketing department

Steve Jones - Mon, 2014-07-14 09:10
In every change there are hype machines that over play and sages who call doom.  Into the Big Data arena steps David Searls to proclaim that Big Data is a myth and simply hype which is set to burst in an article over at ZDNet. But big data, he said, is nothing more than the myth that collecting vast amounts of data can help companies know customers better than those customers even know

"Essentially, all models are wrong. Some models are useful."

The Other

Greg Pavlik - Thu, 2014-07-03 11:33
It is the nature of short essays or speeches that they can at best explore the surface of an idea. This is a surprisingly difficult task, since ideas worth exploring usually need to be approached with some rigor. The easy use of the speech form is to promote an idea to listeners or readers who already share a common view - that is one reason speeches are effective forms for political persuasion for rallying true believers. It's much more difficult to create new vantage points or vistas into a new world - a sense of something grander that calls for further exploration.

Yet this is exactly what Ryszard Kapuscinski accomplishes in his series of talks published as The Other. Here, the Polish journalist builds on his experience and most importantly on the reflections on the Lithuanian-Jewish philosopher Emmanual Levinas to reflect on how the encounter with the Other in a broad, cross cultural sense is the defining event - and opportunity - in late (or post) modernity. For Kapuscinski, the Other is the specifically the non-European cultures in which he spent most of his career as a journalist. For another reader it might be someone very much like Kapuscinski himself.

There are three simple points that Kapuscinski raises that bear attention:

1) The era we live in provides a unique, interpersonal opportunity for encounter with the Other - which is to say that we are neither in the area of relative isolation from the Other that dominated much of human history nor are we any longer in the phase of violent domination that marked the period of European colonial expansion. We have a chance to make space for encounter to be consistently about engagement and exchange, rather than conflict.

2) This encounter cannot primarily technical, its must be interpersonal. Technical means are not only anonymous but more conducive to inculcating mass culture rather than creating space for authentic personal engagement. The current period of human history - post industrial, urbanized, technological - is given to mass culture, mass movements, as a rule - this is accelerated by globalization and communications advances. And while it is clear that the early "psychological" literature of the crowd - and I am thinking not only of the trajectory set by Gustave LeBon, but the later and more mature reflections of Ortega y Gasset - were primarily reactionary, nonetheless they point consistently to the fact that the crowd involves not just a loss of identity, but a loss of the individual: it leaves little room for real encounter and exchange.

While the increasing ability to encounter different cultures offers the possibility of real engagement,  at the same time modern mass culture is the number one threat to the Other - in that it subordinates the value of whatever is unique to whatever is both common and most importantly sellable. In visiting Ukraine over the last few years, what fascinated me the most were the things that made the country uniquely Ukrainian. Following a recent trip, I noted the following in a piece by New York Times columnist Nicholas Kristof on a visit to Karapchiv: "The kids here learn English and flirt in low-cut bluejeans. They listen to Rihanna, AC/DC and Taylor Swift. They have crushes on George Clooney and Angelina Jolie, watch “The Simpsons” and “Family Guy,” and play Grand Theft Auto. The school here has computers and an Internet connection, which kids use to watch YouTube and join Facebook. Many expect to get jobs in Italy or Spain — perhaps even America."

What here makes the Other both unique and beautiful is being obliterated by mass culture. Kristof is, of course, a cheerleader for this tragedy, but the true opportunity Kapuscinski asks us to look for ways to build up and offer support in encounter.

3) Lastly and most importantly, for encounter with the Other to be one of mutual recognition and sharing, the personal encounter must have an ethical basis. Kapuscinski observes that the first half of the last century was dominated by Husserl and Heidegger - in other words by epistemic and ontological models. It is no accident, I think, that the same century was marred by enormities wrought by totalizing ideologies - where ethics is subordinated entirely, ideology can rage out of control. Kapuscinski follows Levinas in response - ultimately seeing the Other as a source of ethical responsibility is an imperative of the first order.

The diversity of human cultures is, as Solzhenitzyn rightly noted, the "wealth of mankind, its collective personalities; the very least of them wears its own special colors and bears within itself a special facet of God's design." And yet is only if we can encounter the Other in terms of mutual respect and self-confidence, in terms of exchange and recognition of value in the Other, that we can actually see the Other as a treasure - one that helps ground who I am as much as reveals the treasure for what it is. And this is our main challenge - the other paths, conflict and exclusion, are paths we cannot afford to tread.

Open Source as religion - when the Bazaar becomes a Cathedral

Steve Jones - Fri, 2014-06-27 09:00
The seminal book on Open Source development "Cathedral and the Bazaar" talks eloquently about the difference between commercial software development and open source development.  In the past few years however there has been another shift, a shift where companies are actively releasing their technology into Open Source as a competitive differentiation.  A claim of 'we are open' because the source

Number one, with a bullet.

Mike Olson - Wed, 2008-01-16 11:43

IDC has just released its annual vendor share report for embedded databases, and Oracle has taken the top spot.

The numbers are compelling: Oracle's share is 23.2%. A cluster of five other vendors have between 9% and 14% each. The rest is spread broadly, with each vendor commanding 2% or less. Oracle's share grew 23.3%, compared to growth of just under 12% for the sector as a whole.

I am glad to see this for a bunch of reasons. As Vice President of Embedded Technology at Oracle, I take a personal interest, of course. Oracle Berkeley DB, which Oracle acquired with Sleepycat in 2006, is aimed squarely at the embedded space. I have long maintained that embedded opportunities represent a significant source of new revenue and growth. Computers have escaped the data center, and special-purpose systems are getting deployed in living rooms, in the walls of buildings and in shirt pockets. There is an enormous amount of data travelling over networks and touching these systems.

The key to our success in the embedded space has been to assemble a family of products that address a wide range of requirements. A manufacturer building mobile telephone handsets needs to store crucial information reliably. So does a vendor building an optical network switch, and an ISV developing high-performance equity trading systems for financial markets. The three have very different requirements, though, and it's unrealistic to expect any single product to satisfy all of them.

All of our database products -- Oracle Database, Oracle TimesTen, Oracle Berkeley DB and Oracle Lite -- can be embedded in partner systems and deployed invisibly to end users. All contributed to our number one ranking by IDC.

It's not just the technology that has made us successful, though. The people who choose and deploy embedded databases are software developers. In the enterprise, we generally talk to DBAs and CIOs, but in the embedded world, we talk to architects and CTOs. Those conversations are different, and we have had to develop new expertise and new strategies as we have pursued embedded customers. Over the past several years, we've concentrated on building the technical, support and sales expertise necessary to win embedded business in countries around the globe. IDC's vendor share numbers suggest that we're doing okay.

Congratulations to Oracle's Embedded Global business team, and to the product development and support groups for all four products! This is a tremendous accomplishment.
